INSULATING MECHANISM Filed July 14, 1934 BY swx ATTORNEY.

PATENT OFFICE 3 Claims.

This invention relates to insulating mechanisms and has special reference to such a device for the protection of the head of one receiving treatment of the hair necessitating the application of heat, such, for example, as the administration of a permanent wave.

The principal object of the invention is to provide a more efficient and practical device of this character, and one particularly adapted for the circulation of liquid as the cooling medi- Other objects and advantages of the invention will appear in the following description thereof.

Referring now to the accompanying drawing, forming part of this application, and wherein like reference characters indicate like parts:

Figure 1 is an underside view of one of the cooling discs;

Figure 2 is a section taken on the line 2-2, Figure 1;

Figure 3 is a reduced under plan view of a group of the discs showing the termini of the hose connection in section;

Figure 4 is a side elevation of the distributing or manifoldunit;

Figure 5 is also a side elevation of the manifold taken at right angles to Figure 4.

Figure 6 is a top plan view of the manifold.

Figure '7 is a schematic view of one practical application of the device.

The instant invention resides not only in the specific construction of a single unit of the device, but in the novel manner of grouping same,

' and the feeding mechanism for a grouped number of units as hereinafter fully described.

I represents a hollow resilient disc, preferably of rubber or the like, the same being provided with a somewhat star shaped slot of opening 2 therethrough; this latter being for the convenient application to the head of a person being treated about a previously assembled and curled tuft of hair, as indicated at 3; for example, such a tuft of hair having been initially coiled about a curling iron of a permanent wavin machine, and in which manner it is intended that the rubber disc shall rest upon, or as closely as possible to the scalp. Then there is applied the felt washer like disc 4, the same preferably being somewhat larger in diameter than the rubber disc to insure proper protection from the heating element, and which disc is flat but having a similarly shaped slot centrally thereof as that shown at 2 in the rubber disc, after which the heating terminal of the permanent wave machine is applied to the curling iron, thus providing a protective insulation between the iron and the head' of the person receiving the treatment.

Now as a convenient form of connection intermediate of a plurality of such units, I have provided arcuately shaped rubber hose connections as shown at 5, they being preferably tangentially opposed as illustrated, and it is apparent that two or more, preferably seven for example, of such units may be thus connected for simultaneous circulation of water or other cooling medium therethrough, the end ones of such an assembly, of course, carrying the terminal connections of the hose, and these latter terminals I prefer to form of the slip-on rubber type, as illustrated at 6, and which may be provided with a binding band 1 to insure against accidental removal of same; or some other convenient form of connection may be employed, if preferred. As the rubber discs I may be made of quite yieldable material they may be assembled on the head when occupying the least space possible for convenience in grouping the required number, and subsequently being expanded will more conveniently adjust themselves.

As liquid is used as the cooling medium, I provide a manifold unit for such purpose as shown at 8, the same being preferably rectangular in shape and of metal construction, though comparatively small, and which unit is divided into two equal compartments 9 and In, as by the division wall II. One of these compartments, for example that illustrated at 9, is provided with an intake connection l2 and eight,more or less, discharge connections I3; while the compartment or chamber In is provided with a single discharge connection l4 and a corresponding number of intake connections 15. This manifold unit may be provided with means such as at It for conveniently attaching it to for example the standard ll of the permanent wave machine, so that the supply hose connection for example may be attached to a faucet as at [9 of a conveniently located lavatory or other form of water supply, while the discharge or waste hose connection 20 from the manifold may be connected with the basin 2| of the lavatory or other waste receiving element.

Now it is apparent that the connections from the manifold, considering for example but one of the series or groups of discs and their hose connections, must supply the cooling medium to and receive the discharge from the group of discs, and that one end of the hose must be attached to the receiving nozzle or connection l3 on the supply side of the manifold, while the opposite end of the hose of such series must be connected to the receiving nozzle or connection l5 to the other side of the manifold, so that circulation of water when turned on at the faucet will occur through all of the units employed simultaneously. Of course, any units or connections not employed must either be shut off or provided with valves or stoppers not necessarily here illustrated.

From the foregoing it is evident that I have provided a simple and eificient means for overcoming one of the most objectionable features with which the profession of hair dressing has to contend, especially in the administering of permanent waves.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. Head insulating mechanism of the type described comprising a hollow disc-like member having a through aperture centrally thereof, said aperture comprising a substantially circular axial opening and a plurality of radially disposed slots extending therefrom towards the periphery of the disc.

2. Head insulating mechanism of the type described comprising a hollow disc-like member having a through aperture centrally thereof, said aperture comprising a substantially circular axial opening and a plurality of radially dispiosed slots extending therefrom towards the periphery of the disc, the opposite walls of the slots converging outwardly to provide yielding means through which tufts of hair may be drawn.

3. Head insulating mechanism of the type described comprising a hollow disc-like member having a through aperture centrally thereof, said aperture comprising a substantially circular axial opening and a plurality of radially disposed slots extending therefrom towards the periphery of the disc, the opposite walls of the slots converging outwardly to provide yielding means through which tufts of hair may be drawn, and a flat insulating disc on top of said hollow disc, substantially the samesize thereof and having centrally disposed apertures therein registering with those in the hollow disc.
